I don’t think the transhumanists and singularitians are wrong, exactly. Mainly their timescale is. They believe their envisioned post-human reverie will arrive in a generation or two while I think it’ll be 5,000 to possibly even a million years hence.

Assuming humans survive that long at all, which right now I’d put at about 10%.

So in a way, I don’t believe in that future at all, because I doubt we’ll survive in any form.

But if we do survive, then I think it’s nearly-inevitable that we’ll change ourselves in now nigh-unimaginable ways, gain better control of matter and space, and expand out into the galaxy. Doesn’t violate the laws of physics and is within the realm of human understanding, so it’ll probably happen just as a random walk across complexity space.
